This is a Centroid T400 retrofit to a 1999 toolroom lathe. The retrofit was completed in March 2013.
The machine has a 10HP spindle motor with low/high (star/delta) winding switching.
It features toolroom-style controls on the apron panel, including dual electronic handwheels; spindle start/stop lever; and cycle start and pause buttons.
The T400 console arm mounted to the cabinet, above the headstock. This put
the console in a similar location to the original BPCT console.
The original Yaskawa servo drives and motors (early Sigma series drives) worked nicely with the Centroid MPU11 and GPIO4D control units, in a velocity control mode.
The MPU11 and GPIO4D fit in the lower-left space previously occupied by
the Bridgeport control unit.
